TANDEM morons IONOSEAPLANE Filed Nov, 25, 1929 3 Sheets-Sheet 3 I flmm A itorney Patented May 13, 1930 v EJ582866 HEIL VINCENT SWEET, OF BUFFALO, NEW YORK TANDEM-MOTORED MONOSEAP'LANE Application filed November 23, 1929. Serial No. 409,308.

The present invention relates to flying machines.

The invention is directed to that general type of aircraft which embodies a fuselage mounted on pontoons and a prime object of the invention resides in the provision of elevators and rudders on the pontoons so that a pusher type of motor may be mounted at the tail of the fuselage to function in cooperation with a puller type of motor at the nose of the fuselage.

A still further very important object of the invention resides in the provision of an aircraft of this nature which is comparatively simple in its construction, strong and durable,

easy to manipulate in the air, capable of landing on land and water and efficient and reliable in use.

With the foregoing general object, and certain other objects and results in view, which other. objects and results will be readily apparent to those skilled in the aeronautical art,

the invention consists incertain novel fea-' tures of design and in construction and arrangement of elements as will be more fully and particularly referred to and specified hereinafter.

Referring to the accompanying drawings, in which similar reference numerals indicate corresponding elements Figure 1 is a side elevation of theair craft embodying the features of my invention,

Figure 2 is a top plan view thereof,

Figure 3 is a front elevation thereof.

Referring to the drawing in detail it will be 'seen that the numeral 5 denotes a fuselage with radial motors 6 and 7 at the front and rear end respectively thereof for operating puller and pusher propellers 8 and 9 respectively. A wing 10 is su diate portion of t by means are mounted below the fuselage one to each side thereof and are connected to the fuselage by means of suitable struts 14.

Each pontoon has thereof and the rear end curves upwardly and has mounted thereon a rudder 16. An elevator 18 is mounted on the rear of the rear ported across the intermee fuselage 5 being braced of struts 11. A pair of pontoons 12' a step 15 in the bottom ends of the pontoons as is clearly illustrated in Figure 2. The wing 10 is provided with a pair of ailerons 19.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of'the invention and the above description.

It is apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

aving thus described my invention, I claim as new is:

A tandem motored mono-seaplane comprising a pair of elongated pontoons, a car body having propelling means fore and aft, supporting studs directly connecting the car body with the pontoons and positioning the former in medial elevated position between the latter, a single supporting wing carried by the said carbody and supported transversely across the upper intermediate portion of the body, a rudder at the rear end of each pontoon, a horizontal stabilizing plane connecting the rudder carrying portions of the pontoons and extending centrally between the upper and lower edges of the rudders, and elevators at the trailing edges of the stabilizing plane.

In testimon whereof I afiix my si nature.
